FREDERIC E. BERTRAND, OF LYNN, MASSACHUSETTS, ASSIGNOR, '.BY MESNEASSIGN- MENTS, TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEWJERSEY,`

A CORPORATION 0F NEW JERSEY.

SOLE-FITTING MACHINE.

To all whom it may concern Be it known that I, FREDERIC E. BERTRAND, acitizen of the United States, residing at Lynn, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in Sole-Fitting Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the saine.

This invention relates to machines for operating 'on shoe soles and likearticles, and

more specifically to sole channeling machines of the general type shownin my prior patents, such for instance, as Patent No. 1,030,- 701i,granted J une 25, 1912.

Machines of this character are designed to perform certain operations ona sole blank,

generally termed sole fitting, necessary to prepare it for attachment tothe upperof a shoe, and the present invention has for its general objectto improve the machines of this type. Stated more specifically, .theinvention aims to increase the life of machines of this type and torelieve the operative of some of the care and attention which is nowrequired of him in using the machines now on the market.

To these ends the invention resides in 'certain novel combinations andarrangements of parts, the advantages of which will be obvious to thoseskilled in this art, and the various features of which will be readilyunderstoodffrom the following description, reference being made to theaccompanying drawings, in which;

Figurel is a view, in side elevation, of an insole channeling machineincluding mechanism embodying the invention in its preferred form g`Fig. 2 is a horizontal, sectional view on approximately the planeindicated by the line 2 2, Fig. 1; and

F ig. 8 is a front elevation of certainof the parts shown` in Fig. 1which relate to the present invention, ,this View being largelydiagrammatic and omitting the adjacent parts of the machine.

In the embodiment of the invention illustrated in the drawings themachine is provided with a work supporting table 2 on which the sole S(Fig. 3) is positioned for Specification of Letters Patent.

Serial No. 83,253.

No. 1,028,801, dated April 23, 1912, by means.

of which it may be lowered to permit the insertion or removal of thesole. Tools of any character suited to the requirements of theoperations to be performed on the sole are mounted in suitable positionin the machine head, and include a channeling knife 4l. Since theparticular tools employed, and the operating mechanisms for them, formno part of the present invention, they will not be specificallydescribed' herein, but reference should be made to my prior patentshereinbefore referred to for a detailed description thereof.

The sole fitting tools are operated through mechanism that is supportedby the frame 1() `and which includes a driving mechanism comprising ashaft 12 rotatably mounted in suitable bearings carried by the frame 10,a loose pulley 14 rotatable on said shaft and constituting the drivingmember for the machine, and a clutch member 16 Vwhich is keyed to theshaft 12 but is slidable along the shaft into and out of Vengagementwith a clutch face formed on the pulley 111.y A coiled spring 18,encircling the hub of the clutch member 16 urges this member toward thepulley. It is obvious that when the clutch member 16 is out ofengagement with the pulley 14 the machine will be rendered inoperative,but when the members 14 and 16 are engaged, the driving mechanism thenbecomes operative to rotate the shaft 12 and operate the tool or toolswith which the machine is equipped. I

The clutch mechanism just described, and consequently the drivingmechanism, is'under the control of a mechanism which includes feelerthat engages the 1sole when it is positioned on the table 2 in readinessfor the tools to operate it. This clutch controlling mechanism includesa reversed or inverted toggle Vmechanism which is duplicated at eachside of the machine. Two parallel toggle arms or links 20 are mounted onopposite sides of the frame 10 (see Fig. 2) and are both pivotallyconnected at their rear ends to a shoe 22 that is located' in a periph-'in the shoe.

lend to one of the lever arms 20, acts through the toggle links 20 and24 in a direction tending to break the toggle and, consequently, toslide the `clutch member 16 toward the pulley 14. This spi-ing thus aidsthe coiled spring 18.

In order to straighten the toggle and thus move the clutch member 16away from the pulley 14, a power driven mechanism is provided whichisbest shown in Fig. 3. This mechanism consists of an eccentric 32, faston the shaft 12 and therefore constantly driven while they machine isinv operation; an eccentric strap 34 arranged to be oscil* lated by saideccentric; a bell crank lever 36 fulcrumed on the machine frame at 38and having one arm pivoted to said eccen.-

tric strap; and a link 40rpivoted to the op- Y posite arm of said bellcrank lever. The freeV end of this link 40 is connected by another link42 to the free end of an arm 44 vdepending from a vrock shaft 46fulcruined toggle link 24,'and this engagement is controlled byadepending feeler 52 which is positioned vertically over the table 2 andis supported for movement normal to the table by two parallel links 47and V56. The

' link47 is fixed on the rock shaft 46 while the link 56 is pivoted'tothe machine frame. It will now be clear from an inspection of Fig. 3that, when the machine is in opera- Vis removed from'under thefeeler'52, thisfeeler dropsunderthe influence of gravity toward theVtable 2 (see'Fig. 1)', Vthus swing-Y ingthe lower end of the arm 44in`acontraV clockwise directionand causing the hook 48, on its next upwardmovement, to slide over the Vupper edge. Vof thelug 50 and to carry thislug downwardly on its next downward stroke. This action moves the toggle20n-f24 from vthe broken position in which it is shown in dotted linesin Fig. 111 into straightened position, as indicated in full lines insaid figure, thus overcoming the ac# tion of the springs 30V and 18 andsliding of engagement with the-pulley 114.' This .action, of course,disconnects the shaft from the driving pulley 14 and interrupts the op-Veration of the driving mechanism.

The table 2 is depressedto remove the sole from it and to place anothersole in position thereon, and when this table next rises, carrying a newsole up under the lower end of the feeler 52, this member israised andoperates through the arms 47 and 44 and the link 42 to move thehook48'out of engagement with the lug 570. andfthus permits the spring30 to break the toggle again, and consequently to move the clutch memtheclutch member 16 along the shaft 12 out j ber 16 into engagement withlthe pulley 14 l u and start the machine into operation. The machine, ofcourse, will continue in operation until the work is removed from engageY ment with the feeler again, whenrthe cycle of operations to stop themachine willA be re-V peated. A Y Y A brake is provided for the purposeof stopping the machine quickly when .the

face with which a correspondingly shaped face'on the end'of the clutchinember`16,VY i

opposite to that which engages vthe pulley 14, is adapted to engage.This brake is mounted immediately in front of the clutch so that it isengaged by the clutch member 16 immediately said memberris freed fromthe driving pulley 14. Since theV clutch member 16 ,is keyed to theshaft 12,.its engagement with the brake rapidly retards and practicallyinstantaneously stops theV rotation of the shaft 12. Inasmuch as'theclutch member 16 is under the control of the feeler 52, the positionofthis feeler deter.- mines whether the driving member 14 'or the brake 60shall .be operatively connectedV to the shaft 12 at any instant.V

It is obvious that the mechanism above described renders the startingVand stopping of the machine entirely automatic andY dependent Ymerelyupon thefpresentation of Y the work to the tools ofthe machine. The

operative thus-is relieved of the careV and attention which otherwisewouldfberequired Y f of him to start and stop. the machine., At

the same time the useless wearVv on the'run-V Q ning parts ofthemachinegwhich otherwise A would be occasioned by the idle ruiming ofYthe machine is eliminated andthe life'of'theY machine is correspondinglyincreased.

While the embodiment of the invention at present preferred has beendescribed above for the purpose of clearly explaining the nature of theinvention, it is obvious that the invention is not limited to embodimentin the specific form shown, but that it may take many forms withoutdeparting from its scope as defined in the appended claims. It will alsobe understood that the invention is not limited in application to thespey cie type of machine shown.
